Try making a precision machine part using a measurement tool based on the meter.

We don't build precision equipment based on fractions of a meter, we build them on fractions of an inch.

A tolerance of one or two thousandths of an inch is an attainable goal. Our system is convenient and easy to work with. Theirs is not.

Their inconvenient system is one reason a typical metric country can not produce precision machine parts.

That's obsolute bollocks. Are you telling me the Swiss can't build a precise watch because their unit of measurement is metric like in all but 3 countries?

Here's a real world example: ISO Hole and Shaft tolerances
A hole for sliding fit between 3 and 6mm hole size has a 0 to -12 micrometer tolerance. That's less than half of a thousandth of an inch tolerance.

You didn't read the post. I said it made sense in certain guns, especially the Glock.

Oh, but I did. And while it may make sense on the production side of things, it makes very little sense on the demand side, which is why there's almost zero demand for this caliber. You didn't read my post.

You are not keeping up with actual results. Four state police agencies have recently adopted 45GAP as their issue pistol. You are obviously out of touch with the Glock community.

Here's the deal. You posted a photoshopped copy of some gelatin penetration chart. I don't know if you posted that as a joke, or if you got suckered, but think clearly for a minute. What 230g fmj .45 round do you know that creates a miniature nuclear mushroom cloud complete with fireball in gelatin? Take a close look at the shattered shell of both the .45 ACP and the .45 GAP, and you'll see they're exactly the same photo. The GAP was louded for about two months, then virtually disappeared from lack of interest, and the fact that a couple of government agencies got conned into wasting money isn't particularly impressive.

Look, if you like the GAP, great! I have a 1911, but I don't belong to that church, and I'm not going to try to sell you one. But as one person already said here, the GAP is a solution looking for a problem, and I couldn't agree more.

By the way, A-O will never build a Tommy for a GAP, and that's important!

Anyway, I'm not trying to dump on you, here's an example. Here in western Washington, the black tail are much smaller than the mule deer of eastern Washington, and the white tail are also larger. My (deer) hunting rifle is a .243, which is quite sufficient. When 6mm hunting rifles were making a splash in the 1950's, there were two to choose from, the 6mm Remington, and the .243 Winchester. Both calibers live today, but you'll find that the .243 to 6mm ratio is about 100:1. Just about every ballistics test and gun writer will tell you that the 6mm Remington is ballistically superior to the .243, even though they shoot the same bullet. Promotion, marketing, who knows. However, the difference is so slight, that the average shooter could care less. I zero at 200 yards, and both, off the bench, will keep sub-moa groups. The 6mm will give you about 20-30 fps more than the same weight factory load for the .243. The point being is that both rounds offered the same thing. One of them won, one lost, and they came out at the same time. Now, the .45 ACP has been around for a hundred years. Outside of a few zealots, what chance does the GAP have, if their selling point to the public is, if you have little hands, this if for you? Got small hands but think the 9mm is too small? Try a .40. It's already filled any gap, pun intended, between the 9mm and the .45. I would feel just as confident firing a .40 as I would one of my .45 's. I say this to people who're considering, I know you're sold on the GAP, and that's fine.

And after having read my previous comment, here's an anecdote. I have several .45 ACP's, most people do. 1911, Taurus double stack, Tommy gun. I also have several 9mm handguns, and I've had most of these guns for quite some time. When I'm at the local gun show or at a gun shop, the guns that pique me are either 9mm or .45 ACP. My kid lives over in Kentucky, and the guns that pique him are .40 S&W. His birthday present years ago was a Baby Eagle .40, and he now has several .40 caliber guns. I have .45 caliber ammo, he has .40 caliber ammo, and we look for and buy for what we already have; these calibers have been here awhile, the .40 not nearly so long as the .45, but the .40 filled a niche, a much more powerful round in the same size gun as a 9mm. The .40 and the .45 have just about identical "stopping" power. Actually, and I say this as a former Navy gunners mate specializing in small arms, a former county deputy, and an NRA designated service rifle master, the 10mm/40S&W/.357SIG was the last round that actually mattered. The 10mm was the best round, the .40 won because of manufacturing issues, and the .357 SIG was like the GAP: a solution looking for a problem. Years ago, the .40 already filled the niche that the GAP wants to.

IMO, you simplify and generalize too much. The .40 beat the 10mm in part because the guns make more sense. Also, most people don't want or need a full dose of 10mm. As far as being a "better" round, I guess it just depends on what you want it for.

The 45GAP is not trying to fit into the .40 niche. It is not part way between a .45 and a 9mm, it is a 45. The 45GAP ballistics are also different than the 40. The 45GAP is a bigger slower bullet, like the 45ACP. For someone who wants 45ACP ballistics in a smaller platform, the .40 is not an acceptable solution.

That's the whole point, there's no niche to fill. The .40 already did, and if the .45 ACP needed a replacement, it wouldn't be the most popular round in history.

Also, you've never addressed the issue of the photoshopped gelatin.

The photoshop is obviously a JOKE.

The GAP DOES NOT replace John Brownings magnificent creation. It is just a way to put a big bore in a small gun - the .40 DOES NOT do that. The .40 is a smaller, faster bullet. The .40 achieves energy comparable to .45 by increasing velocity. That is not what big bore fans want. Big Bore fans want to increase energy by increasing mass, that is the whole point. Mass is constant, velocity is not.

The 45GAP has lower pressure, lower recoil, greater mass, and greater accuracy compared to the 40S&W.

As much as I like, and prefer, the 45ACP, it is not the most popular round in history - The 9mm Luger is more popular.

I don't know why you are having such a hard time with this. Go and hold a Glock 21 and a Glock 37. You will notice a significant difference. Consider the following:

- Glock sells many pistols to police agencies
- Some agencies requested .45's
- The Glock 21 is very large for a service weapon
- Modern science allows for a shorter .45 cartridge
- The Glock 37 uses the new cartridge to make a standard sized gun

How has the experiment worked so far? Well, at this point in it's life the 45GAP has more acceptance than did the 357SIG or the 10mm at the same point's in their lives. Many people, like you, believe the caliber went away. It didn't, and it's not going to. Glock kept the 10mm alive when it had no vested interest in doing so. Do you think it will let it's own caliber die? At least 4 state agencies, and many more municipal agencies, have adopted the GAP already.

As I said before, government agencies wasting taxpayer money isn't impressive. And I never said this round would die. I did say that there's very little interest in it, which is true.
